What command line parameters are you using?
you have to use the /r:System.dll to get it to compile...
try this:
csc /target:winexe /out:eventlog.exe class1.cs /r:system.dll

the /r:System.dll is done automatically when you say csc class1.cs. Also I tried the second option that you told. No luck. But I got VS.NET beta 1 installed on my machine. I created a c# project, built it and its just ducky.
Thanks anyways.

I have built a simple C# Windows Application and it runs on the machine I built it on fine.
I put the .EXE on another machine and tried to run it there it failed. It needed mscoree.dll so I added that to the directory the .EXE is in. Now I'm getting a .NET frame work initialization error. I guess I need to install the .NET frame work (maybe?).
If that is the problem, how do I do that without installing the Visual Studio.NET?

You need to have the .NET runtime installed on target machines [its a 18-19 MB download]

Rick you need to install the .NET framework on the target machine. Developing for .NET brings along awhole slew of new things, including runtime baggage.
If you got VS.NET via an MSDN subscription then you should also have got a CD with the entire .NET Framework on it. Use that on the target machine.
From what I have heard there will be a "service pack" for Windows XP (not sure about 2000, but probably as well) that will include the .NET Framework. This should be released once .NET has gone gold.
Future versions of Windows will have it all built in. I can't wait

I have the next DLL:
".h"
#ifdef BABMD5_EXPORTS
#define BABMD5_API __declspec(dllexport)
#else
#define BABMD5_API __declspec(dllimport)
#endif
// This class is exported from the BabMD5.dll
class BABMD5_API CBabMD5 {
public:
CBabMD5(void);
};
BABMD5_API long WINAPI EncodeText(LPCTSTR p_sPlainText, LPTSTR p_sEncodedText, long nBufferLen);
".cpp"
BOOL APIENTRY DllMain( HANDLE hModule,
DWORD ul_reason_for_call,
LPVOID lpReserved
)
{
switch (ul_reason_for_call)
{
case DLL_PROCESS_ATTACH:
case DLL_THREAD_ATTACH:
case DLL_THREAD_DETACH:
case DLL_PROCESS_DETACH:
break;
}
return TRUE;
}
BABMD5_API long WINAPI EncodeText(LPCTSTR p_sPlainText,LPTSTR p_sEncodedText, long nBufferLen)
{
CMD5 m_md5;
// Here get the user name always in uppercase,
// and if we've got a NULL pointer then we fill it with an empty string
// We've done this way because of Visual Basic null strings
if(p_sPlainText!=NULL)
m_md5.setPlainText( _strupr((LPTSTR)p_sPlainText) );
else
m_md5.setPlainText("");
if (nBufferLen>32)
// and return the encoded string also un uppercase
strcpy(p_sEncodedText,_strupr((LPTSTR)m_md5.getMD5Digest()));
return 33;
}
// This is the constructor of a class that has been exported.
// see BabMD5.h for the class definition
CBabMD5::CBabMD5()
{
return;
}
I need call the function "EncodeText" from C# to do it I typed the next code:
[DllImport("BabMD5.dll")] static extern long EncodeText(
string p_password,
[MarshalAs(UnmanagedType.LPTStr)]string p_encText,
long p_size);
...
try {
string sText = "";
EncodeText("testestest",sText,33);
} catch(DllNotFoundException exc) {
Console.WriteLine(exc.ToString());
} catch(EntryPointNotFoundException exc) {
Console.WriteLine(exc.ToString());
}
But I doesn't return nothing. Anybody know what's happen?
Thank you.

The first thing that I've made was read the article, It's a good article where I found how to avoid the problem of load the dll and the method but my actual problem is that I can load and detect the method but this don't return nothing. I don't know what it's happening.

If you want to return 'sText', you must ref the var.
Try this:
[DllImport("BabMD5.dll")] static extern long EncodeText(
string p_password,
ref string p_encText,
long p_size);
EncodeText("testestest",ref sText,33);

Good day. How do I send and receive WM_COPYDATA messages in C# that contain data? In particular, how do I unpack the COPYDATASTRUCT in C# when I get the WM_COPYDATA message? Sample code would be appreciated. Thanks Robert

I have a C# application, where I use a good old COM Object written in VC6. This is the easy part...
The COM Object implements Connection Points, to throw events to the client using it.
I can not get C# to catch those events. I have tried everything I can find in the documentation, but it don't work, the event-functions in C# is never called. 
Anybody have a small sample of how to do this?

Stipulation - I'm doing this with notepad and the SDK.. no Visual Studio.
How do you get a spawend dialog to interact with the main form? With VB, it was as easy as referring to the main form and it's properties. It doesn't seem to be as easy with c#.. example code..
<pre>
using System;
using System.Windows.Forms;
using System.Drawing;
class MainForm : Form {
Button btnGo = new Button();
public MainForm() {
Text = "Main Form";
btnGo.Location = new Point(100,100);
btnGo.Name = "btnGo";
btnGo.Text = "Go";
btnGo.Click += new EventHandler(btnGo_Click);
Controls.Add(btnGo);
Opacity = 80;
}
public static void Main(string[] args) {
Application.Run(new MainForm());
}
private void btnGo_Click( object sender, EventArgs e) {
Form2 x = new Form2();
x.ShowDialog();
}
}
class Form2 : Form {
Button btn1 = new Button();
public Form2() {
Text = "This is the second form";
btn1.Text = "Do it";
btn1.Location = new Point(100,100);
btn1.Click += new EventHandler(btn1_Click);
btn1.Name = "btn1";
}
private void btn1_Click(object sender, EventArgs e) {
//Here is where I want to modify the main form.
// How would I go about changing, let's say, the Title?
}
}
</pre>

Try this. I added 2 lines of code, one in the "Owner" form (btnGo_Click), and one in the "Owned" form (btn1_Click). Good Luck!
class MainForm : Form
{
Button btnGo = new Button();
public MainForm()
{
Text = "Main Form";
btnGo.Location = new Point(100,100);
btnGo.Name = "btnGo";
btnGo.Text = "Go";
btnGo.Click += new EventHandler(btnGo_Click);
Controls.Add(btnGo);
Opacity = 80;
}
public static void Main(string[] args)
{
Application.Run(new MainForm());
}
private void btnGo_Click( object sender, EventArgs e)
{
Form2 x = new Form2();
x.Owner = this;
x.ShowDialog();
}
}
class Form2 : Form
{
Button btn1 = new Button();
public Form2()
{
Text = "This is the second form";
btn1.Text = "Do it";
btn1.Location = new Point(100,100);
btn1.Click += new EventHandler(btn1_Click);
btn1.Name = "btn1";
Controls.Add(btn1);
}
private void btn1_Click(object sender, EventArgs e)
{
//Here is where I want to modify the main form.
// How would I go about changing, let's say, the Title?
this.Owner.Text = "HOWDY";
}
}

Perfect! Except for the fact I didn't add the control.
Thanks...

In Java, you can create an instance of an object by name by getting the Class object by name, and then calling createInstance() - or something like that.
Is this possible in C#? It looks like I might be able to do it through assemblies, but I'm not sure.
Application: I want to be able to provide a configuration file that lists the class names of add-ins to load. The app would loop through these names, create instances and use them.
I know I can do it with COM, but I'd rather not subject the authors of add-ins to writing COM servers.
Anyways, is this possible?

You can use the Assembly class to load assemblies at runtime, the GetType function to get an object's type, and the Activator.CreateInstance static function to create an object of that type:
Assembly a = Assembly.Load("MyLibrary");
Type t = a.GetType("MyLibrary.MyClass");
object obj = Activator.CreateInstance(t);

How to search for files/folders and adding all the found filenames to a collection.
For exemple :
Search all "*.url" files on "C:"
Thanks

The things you need is located in the namespace System.IO... I would do it like this:
using System.IO;
public void FindFiles (string path)
{
if (Directory.Exists (path))
{
DirectoryInfo thisDir = new DirectoryInfo (path);
FileInfo [] files = thisDir.GetFiles ("*url");
DirectoryInfo [] subDirs = thisDir.GetDirectories ();
foreach (FileInfo f in files)
{
}
foreach (DirectoryInfo d in subDirs)
{
FindFiles (d.FullName);
}
}
}

My boss says...
I need to create MS Word 97/2000 documents using C#.
In other words, we want to use MS Word to display the output from a C# program.
Things will change in the Word document like address, date, From, To and some accounting data pulled from our Oracle database.
Of course, I'm a 3 month newbie to .NET & C# programming.
Can anyone kick start me with some examples/code/book recommendations?
I've got my "Learn C# in 21 Days" book ordered...
